Silicon photonics is a promising technology to scale offchip bandwidth in a power-efficient manner. Given equivalent bandwidth, the flexibility of switched networks often leads to the assumption that they deliver greater performance than point-to-point networks on message passing applications with low-radix traffic patterns. However, when optical losses are(More)
We have investigated the selective epitaxial growth of GeSi bulk material on silicon-on-insulator substrates by reduced pressure chemical vapor deposition. We employed AFM, SIMS, and Hall measurements, to characterize the GeSi heteroepitaxy quality. Optimal growth conditions have been identified to achieve low defect density, low RMS roughness with high(More)
—The technologies associated with integration and packaging have a significant impact on the overall system. In this paper, we review a silicon photonic " macrochip " system and its associated packaging that will allow dense wavelength-division multiplexed optical links to be intimately integrated and co-manufactured with the switching electronics. For this(More)
